Description

Technical Field

[0001] This application relates to the field of cargo handling equipment, and in particular to a modular cargo pallet. Background Technology

[0002] Precision mechanical material handling systems are an important component of modern industrial production, widely used in manufacturing, logistics, and other fields. With increasing automation, pallets, as key equipment for material transport, directly impact the efficiency and stability of the entire production line through their design and performance. Especially when handling complex and diverse mechanical materials, pallet design must not only meet basic handling requirements but also possess high precision, high stability, and the ability to adapt to various materials.

[0003] Currently, to improve the stability and reliability of cargo pallets, the industry typically employs the following methods: First, using traditional belt drive systems, which are simple in structure and low in cost, suitable for light loads and low speeds; second, using gear drive systems, which offer high transmission accuracy and load-bearing capacity, suitable for medium loads and high speeds; third, utilizing air flotation technology, which reduces friction through gas suspension to achieve high-precision positioning, particularly suitable for ultra-precision machining applications; fourth, using ball screw drives, which enable precise position control and high load-bearing capacity, suitable for heavy-load and high-precision scenarios; and fifth, combining chain and sprocket drives, a combination that ensures high precision while improving load-bearing capacity and impact resistance.

[0004] However, all the aforementioned traditional methods have certain limitations in practical applications. For example, belt drive systems are prone to slippage, leading to inaccurate transmission, especially when carrying heavy or irregularly shaped materials; gear drive systems are inconvenient to maintain due to their complex structure and have poor adaptability to diverse materials. Furthermore, while air flotation technology and ball screw drives can achieve high-precision positioning, their high cost and technical difficulty have limited their widespread adoption. Therefore, how to reduce manufacturing and maintenance costs while ensuring high precision, and how to adapt to various types and shapes of materials, has become an urgent technical problem to be solved.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0030] The inventors of this application have discovered that various traditional material conveying methods have certain limitations in practical applications and cannot meet the needs of complex production environments. Therefore, this application mainly adopts a combined cargo pallet solution, which achieves the effect of improving the stability and accuracy of material conveying. The following is a further detailed description of this application.

[0031] Example 1

[0032] Combination Figures 1-4 As shown in the embodiment of this application, the combined cargo pallet includes a support base 1, a main drive shaft 2, a driven drive shaft 3, a motor 4, a drive wheel 6, a drive belt 7, a raised strip 8, and a support plate 9. The cooperation relationship between the components is as follows:

[0033] Specifically, support base 1 is used to secure the basic structure of the entire pallet system. Support base 1 can be made of metal materials, such as aluminum alloy or stainless steel, to ensure sufficient strength and durability. Support base 1 may also be equipped with shock-absorbing pads to absorb vibrations generated during operation and improve the stability of the system.

[0034] The main drive shaft 2 and the driven drive shaft 3 are rotatably mounted at both ends of the support base 1, and are arranged in parallel. The main drive shaft 2 and the driven drive shaft 3 can be mounted on the support base 1 via bearings to reduce friction and wear. The function of these two drive shafts is to transmit power, enabling the drive belt 7 to operate normally. The diameters of the main drive shaft 2 and the driven drive shaft 3 can be selected according to actual needs; generally, a diameter between 20mm and 50mm is suitable.

[0035] Motor 4 is fixedly mounted on one side of support base 1 and is connected to main drive shaft 2 via reducer 5. The selection of motor 4 should be determined according to the required torque and speed. Common types of motor 4 include DC motors and AC servo motors. The function of reducer 5 is to reduce the speed of motor 4 and increase output torque. Common types of reducers 5 include planetary reducers and worm gear reducers. This configuration can effectively improve the operating accuracy and stability of the system.

[0036] The transmission wheels 6 are divided into two groups of three, which are fixedly mounted on the main drive shaft 2 and the driven drive shaft 3, respectively. The material of the transmission wheels 6 can be steel or engineering plastic, depending on the load requirements. The diameter of the transmission wheels 6 also needs to be adjusted according to the actual situation, generally between 30mm and 80mm. In this embodiment, the transmission wheels 6 are designed to be standard circular.

[0037] There are three transmission belts 7, which are respectively wound around the drive pulleys 6 of the main drive shaft 2 and the driven shaft 3. Each transmission belt 7 has a raised strip 8 on its outer surface. In this embodiment, the raised strip 8 is arranged along the direction of movement of the transmission belt 7 and is arranged around the outer surface of the transmission belt 7. The raised strip 8 is designed to enhance the engagement force between the transmission belt 7 and the support plate 9, preventing slippage. The raised strip 8 covering the entire transmission belt 7 increases the friction between it and the support plate 9, and the direction of the raised strip 8 can prevent lateral displacement of the support plate 9. The cross-section of the raised strip 8 can be designed as rectangular, trapezoidal, or other shapes to adapt to different working conditions. Common raised strip 8 heights are between 10mm and 20mm, and widths are between 10mm and 20mm. The raised strip 8 can be made of wear-resistant materials such as rubber and nylon. It is worth noting that in this embodiment, each transmission belt 7 has two raised strips 8, which are arranged parallel to each other, further increasing the stability of the fit between the support plate 9 and the transmission belt 7. At the same time, when using the transmission belt 7 alone for transportation, it can also increase the friction between the transmission belt 7 and the material, ensuring stable material transportation.

[0038] The support plate 9 is detachably mounted on the transmission belt 7. A groove is formed on the lower surface of the support plate 9, which engages with the corresponding rib 8. The support plate 9 can be made of metal or high-strength plastic, with a thickness between 10mm and 20mm. The shape and size of the groove should match the rib 8 to ensure good engagement. The length and width of the support plate 9 can be adjusted according to actual needs to accommodate materials of different sizes.

[0039] The modular pallet in this embodiment features a robust and reliable transmission structure achieved through the support base 1, main drive shaft 2, driven drive shaft 3, and multiple drive belts 7. The design of multiple drive wheels 6 and drive belts 7 enables multi-point synchronous drive, enhancing stability during transmission. Furthermore, the uniform specifications of the multiple drive belts 7 allow for direct placement of larger materials for transport. With the addition of the support plate 9, smaller, scattered materials can be uniformly placed on the support plate 9 for transport. The interlocking of the protrusions 8 on the outer surface of each drive belt 7 and the grooves formed on the lower surface of the support plate 9 effectively prevents slippage or detachment of the support plate 9 during movement, further improving safety. The detachable support plate 9 design facilitates replacement and maintenance, extends equipment lifespan, and its quantity can be adjusted according to actual needs, improving transport efficiency.

[0040] Example 2

[0041] As another embodiment of this application, unlike Embodiment 1, it combines... Figure 4 As shown, the combined cargo pallet of this application adds a limiting clamp 10 and a tensioning mechanism to further improve the stability and reliability of the system.

[0042] Specifically, the limiting clamps 10 are fixed to the support base 1 and are arranged in pairs on both sides of the corresponding transmission belt 7. The main function of the limiting clamps 10 is to restrict the lateral movement of the transmission belt 7 and prevent it from deviating during operation. The height of the limiting clamps 10 is lower than that of the transmission belt 7 to ensure effective restraint without affecting the contact between the transmission belt 7 and the material or the bearing plate 9. The limiting clamps 10 can be made of metal materials, such as aluminum or steel, and can also be coated with an anti-rust coating to extend their service life.

[0043] The tensioning mechanism is fixedly installed on the lower end face of the support base 1 and connected to the corresponding transmission belt 7. Each tensioning mechanism includes two tensioning plates 11 arranged relatively parallel to each other, a tensioning wheel 12, and a fastening bolt 13. The tensioning plates 11 are provided with vertically arranged slotted holes 14. The fastening bolts 13 pass through the two slotted holes 14, and the nuts and end caps of the fastening bolts 13 abut against the outer end faces of the two tensioning plates 11 respectively, thus fixing them in place. The tensioning wheel 12 is rotatably mounted on the fastening bolt 13 and is connected to the corresponding transmission belt 7 for transmission. The function of the tensioning mechanism is to adjust the tension of the transmission belt 7, maintain appropriate preload, and prevent loosening and tooth skipping. The diameter and position of the tensioning wheel 12 can be adjusted according to actual needs to achieve the best tensioning effect.

[0044] Example 3

[0045] As another embodiment of this application, unlike Embodiment 1, the combined cargo pallet of this embodiment changes the direction and number of the convex strips 8 and the connection method of the transmission belt 7 and the transmission wheel 6 to adapt to more complex material handling needs.

[0046] Specifically, the ribs 8 are arranged perpendicular to the direction of movement of the drive belt 7, with two parallel ribs 8 on each drive belt 7. This design provides stronger longitudinal locking force and is suitable for heavy or irregularly shaped materials. The height and width of the ribs 8 can be adjusted according to actual needs. For example, for heavy materials, the height and width of the ribs 8 can be appropriately increased to improve grip and stability.

[0047] The inner surface of the transmission belt 7 is toothed, and the transmission wheel 6 is a sprocket. The transmission belt 7 is meshed with the transmission wheel 6. Compared with the round wheel in Embodiment 1, the sprocket has a greater transmission force and is less likely to slip due to excessive material weight.
